feat: add nop destination and cleanup deprecated components

[blumamir]

This PR:

• removes the deprecated and unused logging exporter, which is replaced with the debug exporter which we do use.
• removed the deprecated ballast extension which we don't use and is deprecated in favor of GOMEMLIMIT which we do use.
• adds the nop exporter which is useful for development and testing (for example - load scenarios)
• adds documentation in CONTRIBUTING.md regarding how to use the debug and nop destination for development.

Cool idea!
nit: I think adding it as a target in Makefile will be more convenient than documenting in markdown file
